Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
Allpowers R1500 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R1500 has 300W more surge headroom (3000W vs 2700W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti AC180 is 0.1 lb lighter (37.4 lb vs 37.5 lb).
We'd skip the Bluetti AC180 in this matchup. It costs $100 more than the Allpowers R1500 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
A solid mid-size unit that competes on price rather than any standout spec. 1152Wh is a useful step above the 1kWh crowd.
Best for: Buyers who catch it on sale and want slightly more than 1kWh.
Where it falls short:
- 37.4 lb is heavy for its capacity
- 2700W surge is mid-pack
- Not expandable
A well-priced 1.1kWh with a real 1,800W output and fast charging, a common budget pick for home backup starter kits.
Best for: First-time backup buyers who want 1,800W output cheap.
Where it falls short:
- 37.5 lb for 1.1kWh
- Not expandable
